Aganju (known as Agayú, Aggayú, Aganjú or Aganyú in Spanish speaking counties) is an Orisha. He is syncretized with Saint Christopher in the Lucumi religion also known as Santería. In Yoruba language, aginjù (not Aganjú) means a wilderness, inhospitable habitat or impenetrable locale.

Aganju is strongly associated with Shango. In some traditions Aganju is described as Shango's father; in other traditions, he is described as Shango's brother. Both Shango and Aganju were, at one time, rulers of the Oyo empire who became deified.

In the Yoruba areas of Nigeria and Benin Republic, Aganju is known as a deified warrior king from the town of Shaki in the present-day Oyo State of Nigeria. He was said to walk with a sword and is said to fight by shooting fire, as opposed to Sango who fights with thunderstones and lightning. Shaki is in the savannah area of northern Yorubaland that has monoliths and boulder outcroppings.

In the Caribbean, Aganju is a volcano deity for the practitioners of Santeria/Lucumi religion. But there are no volcanoes in either the Caribbean nor Yorubaland, nor is Aganju associated with volcanoes among the Yoruba people. However, the Biu Plateau in the highland area of Northeastern Nigeria contains a number of extinct volcanoes. Biu Plateau is about 580 kilometres (360 miles) from Abuja, the capital of Nigeria and about 720 km (450 mi) from Oyo, Nigeria. These extinct volcanoes have long been extinct and they are also far from Yorùbáland geographically. It is most likely that the association of Aganjú with volcanoes in the Caribbean is not older than the last century among creoles. And this due to Aganjú's supposed temperament coupled with the relationship with Oroíña of Orisa faith (Ọ̀rànmíyàn in Yorùbá language).

In the Afro-Brazilian tradition of Candomblé, Aganjú is worshiped as a manifestation or quality of the Orisha Shango, often called Xango Aganjú. Aganjú represents all that is explosive and lacking control. He is also nicknamed "Xangô menino" among Candomblé practitioners.
